FILLING-REPLENISHING LOOH.

Application tlled'l'annary a, 1923. Serial in. 511,154.

T 0 all whom it may concern Be it known that I, Tnomas L. (HAP MAN, a citizen of'tbe United States. residing in Bondsville, in the county of Hampden and State of Massachusetts. have invented an Improvement in Filling-Replenishing Looms, of which the following de- Scription, in connection with the accompanying drawings, is a specification, like charms tors on the drawings representing like parts.

This invention relates to filling replenishing looms, and more particularly to means for preventing portions of the filling extending from an e'ected filling carrier after re lenishment firom being drawn into the she In looms of the filling replenishing type, it is now the common practice to cut or sever the filling between the cloth selvage and the filling carrier to be ejected when the filling is to be replenished. Thus, when the filling carrier is ejected. a trailing end of filling extends from the ejected carrier through the shuttle eye and sometimes longitudinally of the shuttle box and is liable to be drawn into the shed when the shuttle is again picked and produce imperfect- Many attempts have been made to mg carried into the shed and some of these have provided mechanism for catching the filling between the ejected filling carrier and shuttle, whilc others have sought to withdraw the trailing end of filling. Such mechanisms, however, add to complication in the loom parts, or uire structural conditions not always desirable.

In accordance with the prcsent invention I. very simple and effective means is re ,7 vided for catching and holding the fil ing and between the ejected filling carrier and shuttle box, so that when the shuttle is picked such and will not be drawn into the shed, and consists of a brush which is' Fig. l is a perspective view at the replenishing side of the loom, having certain arts broken away, and showing features 0 the presentinvention;

Fig. 2 is an enlarged cross-sectional view through the shuttle box;

Fig. 3 is a plan view of the replenishing shuttle box with parts broken away to show other parts beneath; and

Fig. 4 is an enlarged perspective view of the replenishing shuttle box and showing the filling catching and holding brush extending into the passage-way or the filling carrier to be ejected.

n looms of the filling replenishing type which employ a feeler mechanism, replenishment is usuallyealled prior to complete exhaustion of the filling in the running shuttle, and when the filling carrier or bobbin to be ejected is thrown fnom the shuttle in the replenishing box by the incoming full filling carrier it is passed downwardly into a receptacle beneath, but the v end 0 he fillin leading from the ejected filling carrier 0 ten still remains threaded through the shuttle eye and is liable to be drawn into the shed and form an imperfection in the cloth.

The replenishing mechanism, in accordance with the present invention, may be of any usual type, and as shown, com rises the hopper 1 in which a series of I09, ed filling carriers 2 are supported. The hopper 1 is rotated from time to time to place the tilling carrier in position for transfer by call mechanism actuated on call for replenishment; The transferrer 3 is mounted on a rod or dead shaft 4 supported by the hopper stand, as usual, and has an arm 5 connected to a dog 6 for actuation of the transferrer by a bunter on the lay to efiectreplenishment of filling. These parts may all be of any usual or desired construction;

The lay i is provided with a shuttle box 8 at the replenishing side of the loom and has an opening 9 extending through the bottom of the shuttle box for the assage of the filling carrier to be ejected w on replenishment of filling is effected. .The shuttle 10 which carries the filling carriers by the usual holding jaws is also provided with an opening ll for the passage of the ejected fillin carrier, and below the open ing for the lling carrier is a chute 12 for directing the ejected filling carrier away from the going parts of the loom and preterably into a cam or receiver beneath. All the parts thus far described may be of usual construction.

In accordance with the present invention, a brush is secured to the lay in such position that the bristles or brush elements extend transversely partially across the passage-way for the ejected filling carrier and since the bristles or brush elements are of a yielding nature they form no obstruction to the free passage of the ejected filling carrier.

In the present instance of the invention, the brush consists of a bar 13 which extends lon itudinall of and below the shuttle box an is provi ed with a. series of bristles or brush elements 14 which, as indicated in Figs. 2, 3 and 4. project into the opening or passage-We for the ejected filling carrier. The bar 13 15 secured to the under side of the shuttle box by screws 15, the construction being such that when a filling carrier is ejected from the shuttle, as indicated in Fig. 2, the ejected filling carrier 16 passes down- A wardl through the opening or passage-way provi ed therefor and may come in contact with the bristles or brush elements 14 which extend into the mssage-way, so that the filling end a, which extends from the ejected filling carrier through the shuttle eye 17, will be en aged by the bristles or brush elements an frictionally hold the trailing end of the filling so that when the shuttle is again picked the trailing end of the filling will be held by the brush, and as the shuttle is irked will cause the trailing end to be unthreaded from the shuttle eyeand not carried into the shed.

When the filling has reached a degree of substantial exhaustion and the filling carrier is ejected from the shuttle during the replenishing operation, the filling a ma lead from different points longitudinally o the filling carrier, and .to insure that the filling leading from the ejected filling carrier shall be engaged by the bristles or brush elements regardless of the position longitudinally of the filling carrier from which the filling end extends, the brush is preferably made of suflicient length longitudinally box to engage the filling. As shown the of the shuttle brush is preferably formed of a length coincident or aproxiniately equal to the filling bearing portion of the li ling carrier. as

best illustrated in Fig. 3.

It may sometimes be desirable to with draw the filling entirely from the brush and shuttle box so that on subsequent picks of the shuttle the trailing end of the filling may not remain in position to be engaged by the shuttle or be liable to be drawn into the shed. and to this end a filling end withdrawing device may be employed in connection with the thread catcher and holder. In the present instance the filling end witlnlrawing device comprises a toothed arm '18, Fig. 1 extending longitudinally of the shuttle and having a frontwardl projecting portion 19 adjustably connected by a bolt 20 and slot 21 to a carrier 22 'which is itself mounted upon a stem or rod 23 projecting laterally from an arm 24 fixed to the stud or dead shaft 4. The arm 24 may be conveniently formed as a projecting member from the tip end support 25 for the filling carriers. but this is not. of course, necessary. The

position of the filling end withdrawing de vice is such that when the lay heats up and is in its front osition, the ortion 18 of the filling end withdrawing .evice enters the passage-way 9 formed in the lay back of the path of the outgoing filling carrier. as indicated in Fig. 2, so that as the lay oes back either on the replenishing or subsequent beats, the filling end withdrawing dc vice is rendered effective to withdraw the trailing end a, of the filling from the brush and also from the shuttle box.

\Vhe'n fillin replenishment is effected by the ejection o the filling carrier to be aban doned and the substitution therefor of a tilting carrier containing a fresh supply. as indicated in Fig. 2. the ejected filling carrier passes downwardly through the bottom opening of the shuttle and the passage-way in the lay and shuttle box, i i-outwardly of the filling end withdrawing device in and the yarn bearing surface of the ejected till-- ing carrier comes in contact wits the bristlesor brush elements 14 of the brush which extends into the passage-way. Owing to the yielding character of thebrush elements it, as indicated in Fig. 2, they present no effective obstacle to the passage of the ejected filling carrier, and since the brush extends longitudinally of the shuttle box to an extent fpretax-ab y'approximate to the length of the lling bearing portion of the filling carrier, it follows that the trailing end of the filling a from the ejected filling carrier will be engaged by the bristles or brush elements 0 the brush regardless of whether the trailing end of filling is at the time near to or remote from the tip end of the filling carrier. When the shuttle is picked after having been replenished, the fili'tioiial Til lltl

lid

engagement of the bristles or brush elements with the trailing end holds the filling so that it is withdrawn from the shuttle eye, and on backward movement of the lay fol lowing replenishment.either immediately or subsequently, the fil ing end withdrawing device will withdraw the filling or trailing end from the brush and also from the shuttle box.

From the construction described it will be clear that the present invention provides a simple and effective means for preventing the trailing end of fillir g leading from an e'ected filling carrier from being drawn into t e shed and that it is readily applicable to any ofthe usual types of filling replenishing looms without alteration therein or the addition of complicated mechanism.

The brush is preferably mounted on the shuttle box below and at the front thereof. and the bristles or brush elements extend rearwardly into the path for theejected illing carrier when replenishment is effeeted.

What is claimed is:

1. In a filling replenishing loom, the-combination of the lay. a shuttle box having an opening for the discharge of a filling carrier, a bnush mounted on'the lay and intersecting the path of the filling carrier as it is discharged from the shuttle to catch the fillin and prevent it being drawn into the shed when the shuttle is again picked.
